BLACKING-MACHINE.

specification of Letters Patent.

Patented Aug., 22, 11916.

Application filed July 2, 1913. Serial No. 777,112.

BER, a citizen of the United States, resid'ing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Blacking-Machines, of which the following description7 in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. i

This invention relates to machines for use in finishing boots and shoes, and particularly to machines for applying blacking, stain, or other finishing material, herein referred .to generically as blacking, to the edges of the heels or soles of boots and shoes'I i The invention has for its general objects to improve' machines of this character with a view particularly to enabling them to produce a better and more uniform quality of work, to meet a greater variety of conditions, and to prevent the staining of parts of the shoe other than the part to which blacking is being applied.

In using machines of this Character there is always a tendency for the. blacking applying brush to load up with blacking to such an extent that it will apply an eXcess of blacking to the work. While this condition can be Controlled satisfactorily with mechanisnis now in use where thin blackings are employed, it is impossible to do satisfactory work with very thick heavy blackings, which many manufacturers prefer to use, for' the reason that these materials pack down the bristles of the brush (particularly if a soft bristle brush is used) thus preventing the brush from fitting the heel or sole edge properly and causing it to apply the blacking unevenly to the edge.

lt is a particular object of this invention to devise a machine that will operate Satisfactorily with the various blackings used in shoe manufacturing. To this end it is proposed to equip the machine with a mechanism for combing the blacking apply'ing brush to prevent the blacking from packing down the bristles in the manner described and to maintain the brush in a proper operative condition.

The invention also provides a novel form of Scraping -mechanism which is designed to remove surplus blacking from the brush and to maintain on'the brush a substantially uniform quantity of blacking.

Machines of this Character' usually include a guide adapted to enter the rand lcrease of the shoe to aid' the operator in guiding the shoe relatively to the brush while the brush wipes blacking upon the edge of the shoe bottom. Usually this guide is employed also to apply blacking to the upper surface of the rand. It is desirable to coat lthoroughly the exposed surfaces of the rand, but it is very important on many classes of work, 'particularly on colored goods, to` prevent any of the stain with which the heel and rand are coated from touching the upper of theshoe. Even if the blacking operation is performed without soiling the upper, the blacking applying devices -may have introduced into the rand creas'ea surplus of-blacking which will be squeezed out of the crease at some later' operation, as for instance in the heel seat beading operation, and Will then ,discolor the upper. With aview to meeting these conditions, the present invention provides a novel scraping mechanism for the rand Grease guide that enables the workman to control nicely the quantity of blacking that will be applied to the rand.

'These and other features of the invention will be clearly understood' from the following description' and the accompanying drawings,`and the novel features will be pointed out in the appended claims.

ln the drawings, Figur'e 1 is a perspective view of a machine embodying the present invention; Fig. 2 is a Vertical sectional view of the machine shown in Fig. 1, the section being takenv through the applying brush; and Fig. 3 is a plan view, partly in section, showing the relative positions of the applying brush and the parts coperating therewith.``

lFor convenience in illustration the features of the invention have been shown as embodied in a machine built in accor'dance with U. S. Letters Patent No. 1,025,523, dated May 7, 1912, but their' use is not limited to machines of this construction.

The machine shown comprises a post 2 land a head 3 having suitable bearings for a main shaft 5. This shaft has mounted thereon fast and loose pulleys 6 and 7, respectively, and a belt shipper 8 is provided to' transfer a belt (not shown) from one pulley to the other to start or stop the machine. V

Fast on the forward end of the shaft 5 is a worm gear 9, Fig. 2, that meshes with and drives a gear wheel 11 which is formed integral with the fianged sleeve 12. The blacking applying brush 13 is clamped between the flange 17 of the sleeve 12 and a nut 18 threaded upon the threaded lower end of said sleeve. This sleeve and the brush re- Volve on a Vertical spindle 19 that is removably held in the frame of the machine between two arms, the upper arm being drilled to receive the spindle and the lower arm carrying a pin 20 which is straddled by the lower end of the spindle to hold the spindle against rotation.

The shaft 5 has fast thereon a worm gear 21 that meshes with a gear wheel 22 which is fiXed on a shaft 23 lying at right angles to and supported below thelshaft 5. This shaft carries a blacking conveying disk"25 that dips into a body of blacking held in a tank 2G.

A 'shaft 28 supported parallel to the shaft 23 in a bearing 29 of the frame and geared to the latter shaft carries at its outer end the rotary rand guiding and blacking conveying device 30 which operates, as more fully shown and described in the above mentioned patent, to convey the blacking from the disk 25 to'the applying brush 13 and also to apply blacking to the rand crease of the shoe. Scrapers 32 which serve to break up and remove the blacking that may have dried on the outer face of the rand guide 30 are carried by a semi-circular yoke 33 adjustably supported on the frame and are spring pressed into engagement with the outer face of the guide.

An arm 34 pivoted at one end on the pin 35 and extending forwardly over the guide A30 carries on its forward end a tubular holder 36 for a scraper 37 of leather, felt, or vsuitable material which is notched to lstraddle the peripheral edge of the guide,

this scraper being adjustable with the holder by a screw 38 to compensate for wear. The arm is operated to maintain the scraper in uniform yielding engagement with the guide by resilient or spring rods 39 which are secured in the frame and bear on a projection extending laterally from the forward end, of the arm 34.

The scraper 37 is shaped to hear both on the surface of the guide 30 that runs in contact with the counter of the shoe, andy also on the surface that engages and applies blacking to the rand, most of the pressure, however, coming on the counter engaging surface. The pressure of the Springs 39 is applied to the arm 34 in a direction tending to move the scraper toward the axis of rotation of the guide 30 and,consequently, holds the scraper yieldingly in engagcment With both surfaces of the guide that engage the Work. The adjustment of the scraper afiorded by'the screw 38 also is toward the axis of the guide and serves to take up -any wear of the scraper. Obviously, this scraper may be shaped to remove more or less of the blacking from the rand engaging face of the guide as the operator may desire. Ordinarily the scrapers 32 will remove all the blacking that it is necessary to take off the rand guide but the additional scraper 37 is i'ntended particularly for use Where unusual care must be exercised to prevent taining the counters, as for instance, on colored stocks, or where there is danger of applying too much blacking to the rand crease.

As above stated, the blacking applying brush 13 tends to become heavily loaded with blacking and if a thick blacking is used the bristles mat together and pack down so that the brush does not apply an even coating to the heel. In order to straighten up thebristlcs of the brush and prevent them .from packing together, I provide a. comb 40 consisting of a hub having two oppositely disposed rows of teeth 41 curved forwardly to enable them to ,dig into the body of the brush and pick up the bristles and straighten them. out. This comb is secured to a sleeve 42 by a nut 43 and the sleeve 42 is mounted fast on the lower portion of a Vertical spindle 45 which is rptatably supported in the frame piece 4G. A spiral gear 47 fast on the sleeve 42 meshes with another spiral gear 48 on the main shaft F4 `tnd drives the spindle 45 and the comb 40 in a direction opposite to the direction of rotation of the brush 13. The ratioof the gears 47 and 48 is such that the comb 40 is driven at a much ner shown in the drawings.

Tn order further to insure the removal of the surplus blacking which otherwise would accumulate on the brush 13, a scraper 49'is mounted rigidly on the comb 40 to rotate therewith. This scraper consists of a thin plate fastened to one face of the hub of the brushA 40 and having its free edge Curved to conform substantially to the peripheral outline of the applying brush 13. This device' during its rapid rotation, engages intermittently the periphery of the' applying brush and supplements the action of the comb in removing the surplus blacking from the brush. The blacking so removed drops back into the tank 26.
